T at whom it may concern:

Beitknown that I, GUS E. OLMSTEAD, a citizen of the United States, residing at Red Cliff, in the county of Eagle and State of Colorado, have invented a new and useful Portable Stove, of which the followingis a specification.

This invention has relation to stovesdesigned chiefly for camp or outdoor life and 1o which are required to be of a portable nature and capable of folding into a small space, so

as to occupy the smallest amount of room possible, which is of advantage in storing and moving from place to place.

I5 The purpose of the invention is to devise a stove of the character and for the purpose aforesaid which can be taken apart and again reassembled and placed in condition for use in a few moments and without requiring the use of tools, bolts, or like fastenings.

The stove comprises an oven composed of sections, whereby it is enabled to be reduced in size, and a damper for controlling the circulation of the flame and hot air, so as to cause 2 5 the products of combustion and heated air to pass over the oven direct to the smoke-pipe or around the oven when it is required to utilize it for the purpose of cooking.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and themi- 3 5 nor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which-- Figure 1 is a perspective view of a portable or camp stove constructed in accordance with this invention, parts being broken away.

Fig. 2 is a longitudinal section. Fig. 3 is a transverse section. Fig. 4 is a plan section.

5 Corresponding and like parts are referred to in the following description and indicated in the drawings by the same reference characters.

The body of the stove comprises a bottom 1, a front 2, arear piece 3, sides 4 and 5, and

a top 6, the latter being provided with a number of stove-holes, which are closed by covers 7. A collar 8 is fitted to the rear portion of the top 6 and is designed to have the smokepipe connected therewith, so as to carry off the smoke to a convenient point and at the same time insure a strong draft being had through the stove when in service.

The bottom 1 has its edge portions recurved, as shown at 9, to embrace outer flanges 10 of the ends and sides of the stove, thereby preventing upward displacementthereof. Transverse bars or plates 11 are applied to the lower side of the bottom and serve to stiffen and strengthen it and prevent warping thereof due to the changes in temperature. These bars or plates 11 extend beyond a side of the stove and have their projecting ends notched, as shown at 12, to receive the lower ends of vertical rods 13, by means of which one side of the top 6 is made fast after the stove has been set up. ,The lower ends of the rods 13 are threaded and receive thumbnuts let, which are adapted to be turned up against the projecting ends of the bars 11 and draw the free edge of the top 6 down upon the top edge of the side 4 and hold it in place.

The top 6 has its edge portion recurved in a similar manner to the bottom 1, the recurved edges 15 thereof embracing outer flanges 16 of the ends and one side. One of the edges of the top 6 is bent at about right angles only, as shown at 17, thereby. permitting this side of the top to pass readily by the outer flange 16 of the side 4:. Ears 18 are secured to the flanged edge 17 of the top 6 and have openings in their pendent ends, through which pass the hooked ends 19 of the rods 13. The top is stiffened and strengthened by means of strips 20, secured to the bottom 'side thereof, said strips crossing and extending about at right angles to each other, so as to brace the top from different points. The transverse strip has its end portions bent, as shown at 2l,so as to engage with the inner braces of 5 the sides of the stove and prevent inward displacement thereof at their upper edges.

The side 5 of the stove is'provided with openings which are closed by doors 22 and 23, the door 22 coming opposite the fire-box or combustion-chamber and the door 23 beingin line with the oven 24:. The opening closed by the door 23 is surrounded by inner flanges 25, against which the four oven-plates bear and are prevented from inward displacement. Vertical strips 26 are disposed in parallel relation and in transverse alinement with the side flanges 25, extending inward from the edges of the opening closed by the oven-door, and these strips act jointly with said side flanges to prevent inward displacement of the front and rear oven-plates. The several ovenplates are similarly constructed and are provided at their ends and sides with flanges 27 and 28, which extend in opposite directions, the end flanges 27 being disposed to project outward from the oven and the side flanges 28 to project inward. These flanges serve to stiffen and strengthen the oven-plates and prevent buckling thereof. The end flanges 27 also serve to secure a close joint between the sides 4 and 5 and the ends of the ovenplates. The bottom plate 29 rests upon transverse rods 30, and the front and rear plates 31 and 32 are placed upon the edge portions of the bottom plate 29 and come within the side flanges 2S and are prevented from outward displacement thereby. As previously stated, the vertical strips 26 engage with the inner faces of the plates 31 and 32 and in conjunction with the side flanges 25 hold said plates against inward displacement. The top plate 33 rests upon the upper edges of the plates 31 and 32 and has its side flanges 28 embracing the upper edge portion of the said plates, thereby supplementing the action of the side strips 28 of the bottom plate 29. Longitudinal strips 34 are secured to the sides of the stove-body and are in the same horizontal plane and engage with the end portions of the plate 33 and prevent vertical movement thereof. The several strips 26 and 34 are angle-plates riveted or otherwise rigidly attached to the sides of the stove.

The transverse rods 30 have their end portions bent and fitted into keepers 35, attached to the sides of the stove. One of the bent ends of the rods has its terminal portion bent to engage with the lower edge of its keeper, as shown at 36, so as to prevent this end of the rods from being disconnected from the stove and lost. The opposite end of the rods 30 is bent at right angles, so as to enable it to be slipped into or removed from the keeper. Vhen one end of the rods 30 is liberated from the keepers, the rods can be turned and folded upon the side 5. The rod 30 nearer the front end of the stove is jointed, as shown at 37, to admit of the free end portion of said rod being folded upon itself. These rods 30 connect the sides near their loweredges and form a support for the bottom plate 20 of the oven.

The front and rear pieces 2 and 3 are prevented from moving inward by stops 3S, applied to the end portions of the sides and engaging with the inner flanged ends of said parts. In the event of it being desirable to use a support for the fuel stops 39 are provided and secured to the sides, so as to form rests for the grate or other support upon which the fuel is to be placed. The precise formation of these stops or rests 39 is immaterial, and they may be provided or dispensed with, as desired. Inasmuch as the fuel used in stoves of this character is of a light nature, consisting, chiefly, of wood, the same is placed directly upon the front end of the bottom 1. Draft for supporting combustion is supplied through an opening in the front 2, closed by a pivoted cover 40.

In order to prevent overheating of the oven and burning of the food at the side adjacent to the fire-box or combustion-chamber 41, the front oven-plate 31 is provided with a baffle-plate 42, the same being curved outwardly between its upper and lower edges and secured at said edges to the corresponding parts of the plate 31 in any desired manner. The air-space formed between the plates 42 and 31 prevents burning and an overheat-- ing of the plate 31.

The stove legs or supports consist of substantially U-shaped wires 43, having their end portions journaled in plates 44, secured to the bottom side of the plate 1. The terminal portions of the wire bails 43 are bent approximately at right angles to the outwardly-extending ends 45, as shown at 46, so as to engage with the lower face of the bottom 1 and limit the outward movement of the bail-shaped supports 43 when turned into an opposite position. The bent end portions 46 constitute stops and limit the outward movement of the bail-shaped supports 43 when the latter are turned so as to assume an outwardly and downwardly divergent relation, as clearly indicated in Fig. 2. These supports or legs 43 fold close against the bottom 1 when the stove is in a knockdown position.

As illustrated most clearly in Fig. 2, the oven is surrounded upon its four sides by a hot-air space, and when it is required to shut off the circulation of the flame and hot air from beneath and in the rear of the oven a damper 47 has been provided and is located at the upper end of the space in the rear of the oven. This damper consists of a plate having its longitudinal edge portion oppopositely flanged. The front edge portion of the damper rests upon the rear portion of the top plate 33 of the oven, and the rear edge is supported by means of a handle 48, secured to the said plate and operating through an opening in the rear piece 3. The pendent flange at the rear edge of the plate 47 limits the forward movement of the damper when the handle 48 is pressed forward. By flanging the edges of the plate in the manner set forth it is possible to construct the damper of sheet metal, and the same will withstand the heat and changes in temperature without warping or buckling.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In a portable and knockdown stove, the

combination of a bottom having its edges recurved, a top having three of its edges recurved and having its remaining or fourth edge bent about at right angles, end and side plates having their upper and lower edges bent outwardly and interlocking with corresponding edges of the top and bottom and adapted to interlock at their ends, perforated ears applied to the flanged or fourth edge of the top, plates secured to the bottom and projecting therefrom on the same side with the perforated ears, rods having their upper ends hooked and engaging with the perforated ears and having their lower ends threaded and adapted to engage with the projecting notched ends of the plates, and thumb-nuts mounted upon the threaded ends of the rods to be turned up against the notched ends of the plates, substantially as and for the purpose set forth.

2. In a portable and knockdown stove, the combination with the stove-body, of the substantially U-shaped folding legs extending across the stove-body and composed of the transverse portions resting upon the floor or supporting-surface, and the sides extending upward from the transverse portions and bent at right angles and forming journals arranged in suitable bearings of the stove-body and having their terminals extended at an angle and engaging the bottom of the same to limit the outward movement of the legs, substantially as described.

3. In a portable and knockdown stove, the combination with the body portion of the stove capable of being dismembered, of a top adapted to interlock at its edges with the upthe said rods, substantially as set forth.

5; In a portable and knockdown stove, the combination of the stove body having an opening in a side provided with inner flanges surrounding the said opening, oven-plateshaving side flanges, the front andrear plates being received between the side flanges of the top and bottom plates, and the inner flanges of the aforesaid opening extending within the space inclosed by the said ovenplates, vertical strips applied to the side of the oven remote from. the side having the oven-door and engaging with the inner faces of the front and rear plates, and longitudinal strips secured to the side plates and engaging with the upper side of the top plate, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
